Description

  The present invention relates to a method of manufacturing a dental prosthesis from a denture base and a plurality of artificial teeth. The invention further relates to a dental prosthesis manufactured using such a method and a kit for carrying out such a method.

  Dental prostheses are generally manufactured using analog methods. That is, denture bases are currently manufactured using an analog system, in which the impression of the patient's jaw without teeth is usually manufactured first. The impression is used to make a mold, which is filled with gum-colored plastic. After the plastic cures, it is finished to the desired shape. The artificial tooth is then inserted into the hollow mold and bonded to the denture base during the molding process.

  In order to produce dental prostheses, artificial teeth are manually placed one by one on a wax base on casts of toothless jaws. In the next step, such wax prostheses are placed in the cell and embedded in a cast, silicone or gel (depending on later processing techniques) to flush the wax base with hot water after the embedding material has hardened This creates a hollow space for the plastic for the prosthesis. During such treatment, the artificial teeth remain in the embedding material. After a suitable plastic is injected or poured into the hollow space and the plastic hardens, a dental prosthesis is obtained. Once the artificial teeth have been placed, the dental technician, or possibly the dentist, adapts and polishes the artificial teeth to the condition of each patient's mouth.

Patent Document 1 discloses a method for manufacturing a dental prosthesis, the method includes the step of cutting the denture from the plastic block based on the impression.

In the dental field, digital manufacturing methods are becoming increasingly important in addition to manual techniques. Here or years, define teeth such as crowns and bridges, CAD-CAM (CAM: Computer Aided Manufacturing, CAD: computer-aided design) are produced by a subtractive cutting method using a technology.

In addition, creation methods such as SLM (selective laser melting) are becoming increasingly important in producing crowns, bridges and models, and stereolithography and DLP (digital light processing) are polymer based dental Products are becoming increasingly important for use, for example, temporary teeth, prostheses, correction devices, mouth guards, drilling templates, dental models and the like. At present, the production of acrylic denture by rapid prototyping (RP) techniques still have significant limitations. For the production of aesthetic dentures with high-quality, multi-color denture or different polymer materials (e.g. enamel and dentin material) made of righteousness teeth only by costly RP machines using a plurality of material chambers, Alternatively only by an expensive adhesive / junction technology, at present it can be manufactured.

Similarly, the production of composites (e.g. cobalt / chromium (CoCr) and polymers) by the RP method is extremely expensive and is not commercially viable at this time.

It is no part partial denture to create a full dentures digitally, to produce me by the CAD-CAM method, for the first time methods already exist, for example, disclosed in Patent Document 2 or 3. Patent Document 4 performs a virtual creation of the teeth in the virtual model, to manufacture the denture base based on the virtual model, discloses a method for producing a denture.

WO 91/07141 German Patent Application Publication No. 102009056752 International Publication No. 2013/124452 German Patent Invention 10304757

Such method has the disadvantage that the dentist or dental technician used have to pay even enormous effort of being positive slightly complement the position and orientation of the artificial teeth in the denture. To such a position and orientation of the fit, it is necessary to machine the occlusal portion of the artificial tooth, or also to polish the denture after eject the artificial teeth should be polished base of artificial teeth.
The object of the present invention is therefore to overcome the drawbacks of the prior art. In particular, a dental prosthesis to be able to adapt in a simple manner to the needs of the patient, the dentist or how users can positively easily complement the position and orientation of the artificial teeth in the denture is provided. In addition, the manufacture of denture base, thus the dental prosthesis is a simple as possible, a complete, yet it is possible to economical manufacture.

The object of the present invention is also achieved by a method of manufacturing a dental prosthesis comprising one denture base and a plurality of artificial teeth according to the following time-series process.
The A) artificial teeth inserted into the denture, said artificial tooth, so that the artificial tooth after insertion into the denture base with limited mobility in the denture, said the denture (1) a binding step, the surface of the denture to be used for fixation of artificial teeth for larger corresponding base surfaces of the artificial teeth, artificial teeth has mobility that is limited in the denture base, the steps,
B) changing the position and / or the orientation of the at least one artificial tooth in the denture base,
The C) artificial tooth comprising the steps of fixing the Oite key crown surface, Ru to finalize fixed in position and / or orientation mutual orientation and position of the artificial teeth are changed, the steps,
D) separating the artificial tooth from the denture base,
The F) artificial tooth comprising the steps of securing in the denture cement or adhesive, the gap between the surface and the artificial teeth denture to be used for fixation of artificial teeth are filled with cement or adhesive step When,
Step G) cement or adhesive cures or a process that will be cured, by Rukoto artificial teeth are firmly connected to the denture, the orientation for denture mutual orientation and position, as well as artificial teeth of prosthetic teeth and position is fixed, the step of separating step, and a key from the artificial teeth.

In the present invention, the key (Schluessel) refers to the relative position of the artificial teeth and the relative position of the artificial teeth so that they do not change their positions or orientation after changing the position and / or orientation of the artificial teeth in the denture base. Ru material or device der to fix the alignment. For this purpose, a silicone mass (Silikonmasse) can preferably be used as a key .

The term crown (derived from "crown" in Latin) means crown direction of the crown and the teeth as terms relating to the position and direction of the teeth, the peripheral region surrounding the occlusal surface and occlusal surface of an artificial tooth Including. In association with it, a limited mobility, artificial teeth means that not entirely freedom-out movable der Rugasono dynamic in denture. Inserted artificial tooth, the angle can be several degrees rotated or tilted against denture on the surface of the denture to be subjected to artificial teeth fixed, or can few tenths displacement of 1 mm.

  The cement or adhesive can be cured by standing for long enough. During curing, a chemical reaction occurs which causes the cement or adhesive to cure. Curing can be actively supported by drying, for example by increasing the temperature.

  The artificial tooth and / or the denture base preferably consist of plastic, particularly preferably polymethyl methacrylate (PMMA).

Artificial teeth may be present are connected individually and / or more groups, or may be present are connected as a complete dental arch. The coupled artificial teeth are firmly connected to each other.

In the method of the present invention, preferably, before step A), fluid viscosity paste (fluide zaehe Masse), preferably wax or clay is denture base surfaces and / or artificial teeth are subjected to a fixed prosthetic teeth is deposited on the base surface, this time, after the artificial teeth are inserted in step a), by fluid viscosity paste is arranged between the denture base surface to be used for fixation of artificial teeth and artificial teeth , the position and / or orientation of the artificial teeth in the denture, fluid viscosity paste, preferably can be changed by deforming the wax or clay.

Fluid viscosity paste, or such waxes preferably sticky wax or clay is room temperature (or slightly above than) in, at the same time it is possible to change the position and orientation of the artificial teeth, the denture position and orientation of the artificial teeth in must have a flexibility which does not change in its weight. In addition, it is preferred that the fluid viscous paste have a degree of cohesion. The adhesive strength or tackiness, as it is impossible artificial tooth is separated from the fluid viscosity paste should be sufficient to hold the artificial tooth.

To achieve this, the fluid viscosity paste preferably has a viscosity between ¹⁰ 2 Pa · s and ¹⁰ 6 Pa · s. Fluid viscosity paste, in particular a wax or clay is placed in the artificial teeth and dentures alcove, a deformation can by hand. Accordingly, the artificial tooth is a movable in a denture bed, retains its position unless another force is applied. Thus, a dentist or user can easily change the position and orientation of the artificial tooth in the denture base by hand.

This measure makes the positioning and orientation of the artificial tooth in the denture base particularly easy.

Fluid viscosity paste, in particular a wax or clay after use, that is, the position of the artificial teeth in the denture and / or orientation is corrected, after the human Koha from denture has him dividing, artificial teeth and denture It should be removable as easily as possible and without leaving a residue.

After step D), prior to step F), the fluid viscosity paste, preferably wax or clay is removed from the surface of the denture to be used for fixation of artificial teeth and / or artificial teeth, preferably heat washed away with water, or be removed with water vapor.

Fluid viscosity paste, preferably the wax or clay is washed from the denture whole and / or entire artificial teeth.

Artificial teeth and / or denture fluid viscosity paste from the surface, preferably by washing the wax or clay, subsequent artificial teeth in the final step of fixing the denture base, stable connection can be achieved. As a result, the dental prosthesis stabilizes for a long time.

According to a further development of the present invention, denture and / or artificial teeth are produced using CAM method or rapid prototyping methods, and / or machined.

In the context of the present invention, with respect to a method of manufacturing a common denture and / or artificial teeth in the manufacturing method for rapid prototyping, using the terminology commonly known as rapid prototyping method. Since the denture and / or artificial tooth is a semi-finished products rather than prototypes, "Rapid Manufacturing" that is sometimes used in such a relationship, "Gene La Restorative Manufacturing", "Rapid Product Development" The terms " advanced digital manufacturing" or " E- manufacturing" can also be used in place of the term "rapid prototyping method ". The denture base is preferably made of rosy or pink plastic and the artificial tooth is preferably made of tooth-colored plastic.

For the manufacture or machining of denture and / or artificial teeth, combination of the manufacturing method using the C AM method or RP method, between the base support surface of the surface and the artificial teeth denture for artificial teeth fixed of the space of play required for mobility of the artificial teeth in the denture in step B), can be put into taken into account by the same calculation within the framework of the CAD method, CAM method or RP method in production can be placed automatically considering thereby has the advantage.

Step B) to be had us, changing at least one of the position and / or orientation of the artificial teeth in the denture is preferably carried out directly by conformance to the patient.

That is, it is obvious that the change of the position and / or alignment or orientation of the artificial tooth should be performed in accordance with the anatomical condition in the oral cavity of the patient.

According to a further development of the invention, in step E) during step D) and step F), the exposed surface of the artificial teeth are swelled by solvent in at least some areas, and / or subjected to a fixed artificial teeth The surface of the denture base to be treated is swollen with the solvent at least in an area.

As a result, a particularly stable bond is achieved between the artificial tooth and the denture base. Since the surface by swelling is liquid or fluid, subsequent bonding process such regions in the newly cured, so that binding a large through a thickness more stable the prosthetic material is achieved.

In a particularly preferred further improvement of the method, in step E), the exposed surface of the artificial tooth is swollen with roughened at least in certain regions solvents, and / or surface of the denture to be used for fixation of artificial teeth at least Ru is swollen with roughened solvents in certain regions.

By roughening the surface additionally, or by slightly rough, surface that could be more rapidly dissolve the solvent. Roughening or slightly roughening the surface can be performed using a solvent. In addition, the effective surface is enlarged with respect to binding by a cement or adhesive, artificial teeth come to be better retained within the denture, as a result, the durability of the dental prosthesis is improved. Furthermore, artificial teeth and denture of the present invention can be washed with hot water or water vapor.

Surface of the denture to be used for fixation of artificial teeth is greater than the corresponding base surface of the artificial tooth (i.e., greater than the corresponding base surface of the supposed artificial teeth located on the surface of the denture) so artificial teeth Have a limited mobility in the denture base, so the use of the method of the invention is particularly advantageous. The artificial tooth is preferably tiltable and / or rotatable up to 5 degrees and / or its position is displaceable up to 1 mm in the denture base. In this case, rotation means rotation around the long axis of the artificial tooth, and tilting means rotation around an axis perpendicular to the long axis.

As a result, born gap required variable volatility in the denture base for the artificial tooth. According to the present invention, the gap is to stabilize the position and orientation of the artificial teeth, fluid viscosity paste at least some regions, in particular is filled with wax or clay preferred.

Further, in step C), the key used is a silicone key.

  The silicone key, such as a silicone mass, has mechanical properties suitable to hold the artificial teeth in the desired new position.

  According to the method of the present invention, it is preferred that excess amounts of cement or adhesive be removed after curing.

A further refinement proposes the use of a self-hardening cement paste, preferably a cement paste made of powder and liquid, particularly preferably a polymethyl methacrylate cement paste , as cement.

Such a method can achieve a particularly stable and easy connection between the artificial tooth and the denture base. It is particularly preferred that the cements have a short swelling time and harden without bubbles. The cement preferably hardens at room temperature and without pressure. In particular, Heraeus Kulzer GmbH's cement Paladur (registered trademark) is preferably has been demonstrated.

Cements or adhesives for final fixation of artificial teeth in denture base should show non-toxic, volume filling, color stability, formulation durability, hydrolysis resistance, volume stability on curing, long Should have a suitable color that is stable for a period of time. Heraeus Kulzer addition GmbH, PMMA cements such Paladur (R), the cement can be for this purpose, Heraeus Kulzer GmbH company Versyo (registered trademark), Heraeus Kulzer GmbH, of Signum COMPOSIT Flow (TM), or Other PMMA-based cements.

  As an adhesive, it is possible to use, for example, a strength instant adhesive or an adhesive which is likewise suitable for filling the volume of the gap between the denture base and the artificial tooth.

Furthermore, according to the invention, prior to step A), partial or complete dentures are created digitally using the CAD method and decomposed into a virtual model of a denture base and a virtual model of an artificial tooth by file division, A denture base and / or an artificial tooth are manufactured using a CAM method based on the virtual model.

As a result, the method can be automated, which can be achieved by the CAD-CAM method.

  Preferably, a methyl methacrylate containing liquid is used as the solvent.

  Alternatively, it is also possible to use ketones such as acetone or alcohols as solvents. However, methyl methacrylate-containing fluids are substantially more suitable for swelling PMMA in artificial teeth and denture bases.

  Such solvents are particularly suitable for swelling materials which are particularly preferred for use in the production of denture bases and artificial teeth.

  The goals of the present invention are also achieved by a dental prosthesis produced by such a method.

Furthermore, the goal of the present invention is also achieved by a kit for performing a such a method, the kit includes a key for securing an artificial tooth that will be oriented in the denture base, artificial teeth and / or denture the solvent for swelling the, preferably a MM a containing liquid.

Kit comprises in denture to provide a movable arrangement on artificial teeth, fluid viscosity paste, in particular a wax or clay.

Furthermore, the kit comprises a cement or adhesive for fixing the artificial tooth in the denture base.

Furthermore, finally, the kit comprises a plurality of pre-processed artificial teeth and / or at least one denture base blank.

Artificial teeth are tightly bound to each other, it may be present as multiple groups or complete prosthesis dental arch. In the latter case, the position and orientation of the prosthesis arches can still be adjusted relative to one another only to the denture base or only between the prosthesis arches .

The present invention, by the present method, can be changed to minimize the position and orientation of the artificial tooth, then, is based on the surprising discovery that it is possible to finish the dental prosthesis in a simple manner. In this regard, the use of the key is important. Since the use of a key can fix the orientation and position of a group of artificial teeth or artificial teeth to each other, preferably when subsequently inserting it into the denture base, the group of people Koha or artificial teeth, have been corrected before Mutual orientation and position are preserved. Upon performing the method, human Koha solid that gap as play between the surface of the constant-exists in the vicinity of the denture in or on its surface, as well as freely within the denture artificial teeth temporarily stable state It is important, or particularly advantageous, to fill the gap with a fluid-viscous paste for positioning.

Swelling of the surface and / or denture surface to be subjected to the fixation of artificial teeth of prosthetic teeth, particularly stable connection between the artificial tooth and denture base can be achieved. The artificial teeth and / or the denture base are preferably swollen with a solution containing methyl methacrylate (MMA) or MMA. The artificial teeth are preferably made of PMMA with a high degree of crosslinking. In dissolve the PMMA material, MMA is dissolve the PMMA, by flow therethrough, the material becomes flexible. As a result, when performing the final binding of the artificial tooth and denture base using a PMMA cement or adhesives rather preferably used, dissolved layer occurs to stabilize the bond. According to the invention, as a result a particularly stable bond is achieved between the artificial tooth and the denture base.

  Exemplary embodiments of the invention will be described in the following on the basis of two schematic drawings, but the invention is not restricted by such embodiments. The drawings are as follows.

FIG. 1 is a perspective view of a lower denture base for carrying out the method of the present invention. FIG. 2 is a perspective view of an artificial tooth inserted into the denture base of FIG. 1 to carry out the method of the present invention.

  FIG. 1 shows a perspective view of a lower denture base 1 for carrying out the method of the invention. The denture base is made of rosy plastic. Color and transparency are appropriately selected to give the appearance of the gums. At the upper part of the denture base 1, there exist a plurality of surfaces 2 for fixing artificial teeth (not shown in FIG. 1).

FIG. 2 shows a perspective view of an artificial tooth 4 inserted in the denture base 1 of FIG. 1 for carrying out the method of the invention. In particular, as shown in FIG. 2, it is preferred that the artificial teeth 4 be separate from one another and not connected to one another. However, by using the mutual bonded to (all bound to each other for each is or group) dental arch of the artificial tooth 4 may perform the method.

The artificial teeth 4 are made of a hard white plastic having a color and transparency suitable for the patient's teeth. Each of the artificial teeth 4 has a crown surface 6 (a heel surface) and a base surface 8. The base surface 8 is fixed to the surface 2 in the denture base 1 for fixing the artificial teeth 4. Since the surface 2 has indexing, the artificial teeth 4 can only be inserted in one specific orientation in the denture base, and each artificial tooth 4 fits only one surface 2.

The surface 2 is somewhat larger than the base corresponding portion on the base surface 8 of the artificial tooth 4. The artificial tooth 4 prior to insertion into the first upper surface 2 of the denture 1, (not shown) has a thin wax layer is in the denture base 1 of the base surface 8 and / or artificial teeth 4 for fixation of artificial teeth 4 Deposited on surface 2 After insertion of the artificial tooth, the wax layer is placed between the denture base 1 and the artificial tooth 4. As a result, the artificial tooth 4 inserted in Ri slightly movable der in the denture 1, therefore, the dentist or user can minimal correction of the position and orientation of the artificial tooth 4 in the denture 1 There is . As a result, the position and orientation of the artificial tooth 4 in the denture base 1 can be matched to the needs of the patient using the manufactured dental prosthesis. Data necessary to determine the orientation and position of the artificial tooth 4 is obtained directly from the patient, or with the aid of CAD methods and / or photograph (3D scan), or is obtained with the aid of the articulator and the impression Ru. Most Briefly, denture base 1 having an artificial tooth 4 inserted is inserted into the mouth of a patient, and to the aligned state of the patient's mouth.

After matching the position and orientation of the artificial tooth 4 in the denture base 1, the artificial tooth 4 is fixed with a silicone key (not shown) by embedding the artificial tooth 4 in a silicone mass. At this time, it shall not apply mechanical forces, such as changes the orientation and position in the artificial tooth 4. Next, the artificial tooth 4 is removed from the denture base 1.

The wax layer is removed from the artificial teeth 4 and the denture base 1. This may be achieved, for example, by flushing with hot water or water vapor. The base surface 8 of the artificial tooth 4 is roughened (for example, mechanically using a sand jet or chemically using an appropriate solvent) and swollen with a liquid containing methyl methacrylate (MMA). Similarly, the surface 2 in the denture base 1 for fixing the artificial tooth 4 is also roughened and swollen with an MMA-containing solution. Available MMA-containing solution, for example, a Heraeus Kulzer GmbH company Palabond (registered trademark).

After pre-processing the surface to be bonded in this manner, the artificial tooth 4 is finally cemented in the denture base 1 while being fixed first to the silicone key. Since cementing is performed using an excess amount of cement, the gap previously filled with wax between the surface 2 in the denture base 1 for fixing the artificial tooth 4 and the artificial tooth 4 is filled with the cement that, but in the gaps do not remain in the hollow space in the base portion side, a gap of even edges gingival / neck region of the teeth of the dental prosthesis produced does not remain. In addition, the excess amount wets the contact surface optimally. The residue of excess cement paste that has been extruded can be removed before and / or after curing.

To the final cementing in the denture 1 artificial tooth 4, self-hardening cement powder powder / liquid system is used. Since the light does not enter only the edge region of the gap between the artificial tooth 4 and denture 1, photocurable cements or adhesives usually do not exhibit sufficient adhesion.

Prosthetic material powder / liquid systems that cure at room temperature, for example, Heraeus Kulzer GmbH company Paladur (R), swelling is rapid, yet (without i.e. excess pressure) without using an autoclave foam at room temperature It is particularly suitable because it cures without

  However, other curing combinations are also conceivable, such as, for example, dual curing cements. In this case, the teeth are fixed for a short time by light, and final curing is performed by an oxidation-reduction reaction.

The method of the present invention can be performed using denture 1 manufactured manually or rapid prototyping method. Likewise, the method is applicable to printing artificial teeth or prosthetic arches.

  The features of the invention disclosed in the above description, the claims, the drawings and the exemplary embodiments are very important in realizing the invention in various embodiments and in any combination of individual features or features. possible.
